MIC 103L Exam 1 Page 1013. Your Loony Uncle in Needles sent you a small, portable Soviet-EraLOMO спу́тник(Sputnik = fellow traveller)Microscope. Your Sputnikhas a single Lens (which has Yellow Ring). On the Base of your Sputnikis an Optical Unit containing what appears to be the Microscope Illumination System. Immediately above this Microscope Illumination System is a Rectangular Glass Plate exactly the same Size as a Microscope Slide. Well, OK; it actually is a Microscope Slide. Black Paint has been applied to the Upper Surface of this Slide such that it has three clear Apertures: one with a Diameter of ~1.5 cm, one with a Diameter of ~1.0 cm, and one with a Diameter of ~0.5 cm. An astonishingly large Metal Lever on the Base of your Sputnikmoves this Black-Painted Glass Plate back and forth in Click-Stops such that the 1.5 cm, the 1.0 cm or the 0.5 cm Aperture can be clicked into Position immediately above the Microscope Illumination System. This Metal Lever on your Sputnikcorresponds to which Control(s) on your MIC 103L Olympus Microscopes?
14. The nasty Flesh-Colored Plastic Carrying Case in which your Sputnikarrived contains a small Allen Wrench. After considerable Experimentation, you eventually discover that you can use this Allen Wrench on two Allen Screws underneath the Stage. These two Allen Screws move what appears to be the entire Condenser Lens System. One Allen Screw moves the entire Condenser Lens System underneath the Stage back and forth in the “X” Axis (“Side-to-Side”); the other Allen Screw moves the entire Condenser back and forth in the “Y” Axis (“Back-to-Front”). Together, these Allen Screws on your Sputnikcorrespond to which Control(s) on your MIC 103L Olympus Microscopes?
15. Underneath the Stage and immediately above the Condenser Lens System of your Sputnikis yet another Glass Plate exactly the same Size as a Microscope Slide. Well, OK, this guy is yet another Microscope Slide (Soviet Optical Engineering was not overly Imaginative -- but it was Solid!). Black Paint has been applied to the Upper Surface of this Slide such that it has three clear Apertures: One with a Diameter of ~1.0 cm, one with a Diameter of ~0.5 cm, and one with a Diameter of ~0.25 cm. A ridiculously small, icky Plastic Lever near the Top of the Condenser moves this Black-Painted Glass Plate back and forth in Click-Stops such that the 1.0 cm, the 0.5 cm or the 0.25 cm Aperture can be clicked into Position immediately above the Condenser Lens System. This small Plastic Lever on your Sputnikcorresponds to which Control(s) on your MIC 103L Olympus Microscopes? A. Condenser Diaphragm Control B. Field Diaphragm Control C. Condenser Focus Knob D. Stage X- and Y-Axis Controls
